So basically the camera's screen came with 2 different types of power options. the first, the most basic one, was a simple cigarrette lighter adapter which plugs into your standard cigarrette lighter port (12V). The connection on the opposite end was a 3.5mm headphone jack. I opted not to choose this option for 2 different reasons. the first is that I hate plugging and unplugging shit. I'm lazy, so sue me. I don't like to have to remember to plug/unplug for a few seconds of use. I mean, seriously, it would be to much trouble to keep on unplugging/plugging every time I decided to reverse it right? the other reason is that I just don't like to have all my 12V plugs occupied. I have my cell phone charger, and sometimes I charge my jumpstart backup battery with the second one (I always carry this around, in case my vehicle or someone else's vehicle doesn't start. I have only used it on my truck once, and I've used it on random stranger's vehicles about 20 times).
The Second connection option was to run it straight to the battery with another cable that came along with the screen. This other plug, had 3 different wire connections, a red, black, and blue wire. Apparently, if you plug it in straight, there is an option to turn have the screen come on by itself (when connected properly) when the vehicle was placed in reverse. This was by far the better choice for me, because it would be easier to just place the vehicle in reverse, and the screen come on.
I chose to install the wires with a simple add-a-fuse from the local Kragens which cost me 10 dollars. this simplified the process because I didn't have to tap into a live wire, and I could just use a pre-existing auxilary fuse connected to the battery. Basically, this will take care of two things. 1: the screen will only have power when the vehicle switch is on, and 2: I won't short my shit out with some funky wiring.
I decided to place the screen on the small square adjacent to the a/c controls, where the passenger airbag switch was located. I screwed in a small hinge next to the airbag switch (So I could still have access to it, and also so I could move the screen to my advantage).
The cable hanging next to it is the one that connects to the screen.
